Largest strongly connected component

CodingAlgorithms & data structuresSenior–Staff~35 min

Given a directed graph with n nodes (0..n-1) and a list of directed edges [u, v], return the number of nodes in the largest strongly connected component. A single node with no edges is its own component of size 1. Constraints: 1 <= n <= 2000; self-loops and parallel edges may appear.

Implement
largest_scc_size(n: int, edges: list[list[int]]) → int

What a strong answer looks like

State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
